Title: Electric weld controlling device
IPC: B23K11/24
Filed: 1934-01-05
Abstract: 431,518. Switching systems for resistance heating apparatus. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (Electric Controller & Mfg. Co. ; 2706, East 79th Street, Cleveland, Ohio, U.S.A.) Jan. 5, 1934, No. 504. [Class 38 (iv)] In electric resistance welding the duration of the welding operation is controlled automatically in accordance with the welding current. Current proportional to the welding current is supplied through a transformer 62 and rectifier 66 to a condenser 70 in series with a resistance 68. When the condenser voltage reaches the breakdown value of one or more neon tubes 72 connected across it in series with the coil of a relay 74, the tubes break down and operate the relay which causes opening of the welding supply circuit. Closure of a push-button 18 energizes a coil 28 for closing the welding circuit at switch 24, coil 28, being in series with contacts 34 on a relay, the coil 46 of which is energized on operation of the relay 74 to de-energize coil 28, short circuit the condenser 70 at contacts 52 and close a holding circuit at contacts 50 so that the welding circuit is held open until the button 18 is released and again depressed. In a modification, push button 18 controls energization of the coil 46 in series with the relay 74 whose contacts are arranged to be normally closed, coil 46, when energized, causing energization of the contactor coil 28 and closing a holding circuit for itself round the push button 18. When the coil 46 is de-energized the condenser 70 is short circuited. Variations in the time-current characteristics of the arrangement are made by varying the condenser 70, the resistance 68, the number of neon tubes in use, or the output of the rectifier 66 as by taps on the secondary of the transformer 62 or variable coupling between the primary and secondary windings thereof. The primary 60 of the transformer 62 may be arranged either in the primary or secondary circuit of the welding transformer 42.

Title: Light heat and sound projectors
IPC: F21V7/00
Filed: 1929-01-07
Abstract: 327,460. Wood, W. G. Jan. 7,1929. Reflectors.-In a heat projector the shape of the lower portion of the reflector is similar to t h a t described i n Specification 301,942 but the two halves on opposite sides of the vertical median plane are angularly displaced by partial rotation (i) about a vertical axis passing through the common proximate focus F1 so that the rays reflected by the two halves overlap each other, as shown in Fig. 4, (ii) about the horizontal major axis A1A1<SP>1> so that the laterally directed rays are deflected below the horizontal, as shown in Fig. 7, or (iii) about both these axes. In the form shown in Fig. 4, the two halves are separated by a horizontal angle 2C, the opening F4<SP>1>, YF4<SP>11> in front of the focus F, being filled by a reflecting surface whose profile follows the elliptical arcs F4<SP>1>Y, and F4<SP>11>Y, whilst one of the two overlapping corners A<1>Y<1>A<11> behind the focus F1 is eliminated. In the form shown in Fig. 7, the two halves are separated by a vertical angle 2<d>, the opening F4<SP>1>A1F4<SP>11> being filled by a reflecting surface which may be a section of an ellipsoid whose axis is A1A1<SP>1> and profile follows the arcs A1F4<SP>1> and A1F4<SP>11>, a section of a paraboloid, or otherwise. The original shape of the upper portion of the reflector mav be the same as that of the lower portion, the overlapping apices caused by the vertical angle 2d being removed, or it may comprise a hemi-ellipsoid having a proximate focus at F1, the opening B<1>Y<1>B<11>, Fig. 4, caused by the horizontal angle 2C being filled with a reflecting surface conforming to the profiles of the two intersecting elliptical arcs- Owing to the vertical angle 2d, the upper portion of the reflector may comprise a complete hemi-ellipsoid P1A1O1 the segments PA,P, and OA,O, being removed, or it may comprise only the segment PA1O. The reflector may be formed in three parts, an upper part U, Fig. 8. and two lower parts S. T. formed with vertical flanges E and with horizontal flanges D, which latter also serve as means for mounting the reflector in the projector casing. The flanges E may be locked together as by means of rivets or screws, or by means of tongues V passing through slots cut in the flanges when forming the tongues. A pair of spring bails 3, 4 are held together by means of a ring 7 formed on one of the bails, and are formed with shoulders 5 and hooks 6 adapted to pass through registering holes X formed in the flanges D and in a shelf extending round the interior of the projector lamp casing.

Title: Improvements in permutation locks
IPC: E05B37/02
Filed: 1944-06-06
Abstract: 607,351. Permutation locks. FISHER, G. R. L. S. June 6, 1944, No. 716/47. Divided out of 607,277. [Class 44] In a permutation lock of the kind having a number of indicia bearing rings acting in conjunction with members such as balls or pawls to provide looking means for a bolt, a dust cap is adapted to co-operate with an additional locking means whereby unlocking can only be effected when the indicia are covered. The invention may be applied, for example, to the permutation lock described in Specification 607,277, in which indicia bearing rings 46, 47, Fig. 1, having internal notches in one of which a ball (52, 53) is located, are rotatable around a bolt 49 which has a longitudinal slot 49b. When the balls are brought into line with the slot, the bolt may be withdrawn from the lock Ratchet mechanism comprising spring-pressed balls 55, 56, Fig. 3, located in a slot in the spacer ring 45 and bearing on the sides of the rings 46, 47 which are formed with radial grooves, hold the rings against displacement by vibration. The indicia on the rings are visible through an aperture 41a, Fig. 1, in the casing 41, which also affords access for setting the rings. The additional locking means is associated with a dust cap or cover 44, Fig. 20, of cylindrical form, with a gap between the ends 44a, 44b, located around the lock casing and held between the end caps 42, 43 (Fig. 1). To set the rings to release the lock, the cover 44 must be rotated so that the gap is over the aperture 41a in the case. In this position, a spring-pressed locking pin 57 housed in a bore in the spacer ring 45 is depressed by the cover 44 and engages in a radial bore 49d in the bolt 49, which cannot thus be withdrawn, even if the rings are correctly set, until the cover has been rotated to bring the gap over the outer end of the pin 57. In order that the combination may be changeable, slots 42f and 45h are provided in the front guide and spacer ring respectively. By depressing the cap 51, the plunger 48 is displaced axially, and if the lock is set for release, balls 52, 53, located in slots 48e and 48f of the plunger, will be carried into slots 42f and 45h. Rings 46, 47 may then be rotated to the new setting, and when plunger 48 is released, balls 52, 53 will be repositioned in different notches.

Abstract: 715,838. Fluid-pressure actuated valves. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Jan. 9, 1953 [Jan. 10, 1952], No. 757/52. Class 135. [Also in Group VI] Gas or vapour flow controlling apparatus, e.g. for breathing equipment, comprises a pressure reducing valve adapted for connection upstream to a source of gas or vapour under pressure and an orifice downstream of the valve, the reducing valve maintaining the pressure upstream of the orifice at such a value compared with the downstream pressure that the orifice operates at a pressure ratio equal to or less than the critical pressure ratio, i.e. in a choked condition. A valve 4 operated by a spring-loaded diaphragm 3, or piston or bellows, maintains a constant pressure of gas in the chamber 9 supplied via inlet 2a. The orifice 8 allows a supersonic flow of gas therethrough so that the mass flow of gas to a receptacle connected at 2b is unaffected by pressure variations in the receptacle.

Abstract: 688,035. Saw-tooth generating circuits; valve oscillators. GENERAL ELECTRIC CO., Ltd. Jan. 12, 1951 [Jan. 12, 1950], No. 845/50. Class 40 (vi). The frequency of a transitron oscillator producing an approximately saw-tooth output wave has a piezoelectric crystal connected to the second control grid, Fig. 2 (not shown), or to the first control grid. In. the circuit shown the crystal operates in series resonance and is shunted by a low resistor 21. A circuit 7 tuned to the crystal frequency or a sub-harmonic thereof, is connected to the second control grid. The output which is derived from a resistor or a transformer in the anode circuit is of approximate saw-tooth form due to the stray capacitance at the anode and the circuit may accordingly be used as a harmonic generator for frequency measuring purposes. When the crystal is connected to the second control grid it oscillates in parallel resonance assisted by negative resistance due to secondary emission at the second control grid.
